Discriminant = 116; Graph crosses the x-axis two times
That depends on the values of the polynomial but in general:- If the discriminant is greater than zero it has 2 solutions If the discriminant is equal to zero then it has 2 equal solutions If the discriminant is less than zero it has no solutions
No, it will be entirely above the x-axis if the coefficient of x2 > 0, or entirely below if the coeff is <0.

88 -Apex ;)
Just the once because it has equal roots of 1/5
Without knowing the plus or minus value of 40 it's difficult to say but in general:- If the discriminant of a quadratic equation = 0 then it touches the x axis at 1 point If the discriminant is greater than zero then it touches the x axis at 2 points If the discriminant is less than zero then it does not touch the x axis
52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.

All real numbers
There are none because the discriminant of the given quadratic expression is less than zero.
